Siphons: reliable protection for measuring instruments

A siphon is a pipe shaped circular or in u-shape, so the medium, whether liquid, gaseous or even steam, can settle within the pipe. Due to its shape, the pipe has a large surface area, which is being cooled down by the ambient temperature. This in turn cools down the medium within the pipe. A manometer shut-off valve can be mounted behind the siphon, which allows you to add a manometer or any other measuring instrument. The siphon protects the measuring instrument reliably from pressure surges or too high temperatures of the media. As a result, the manometer can measure the pressure precisely.

Siphons made of steel or stainless steel acc.to DIN 16828

To ensure longevity of the siphons, they are made exclusively of stainless steel 1.4571 or steel. Additionally, they are produced out of a single piece of pipe, in order to prevent predetermined breaking points. The connection is a ½“ thread. All siphons are being manufactured according to DIN 16828. You can find detailed information such as measurements and temperature range in the data sheets available on the article detail page. NieRuf offers siphons in three designs and three different shapes: tap x union nut, welding end x union nut and welding end x welding end. All designs can be produced circular, in a u- or in a flat u-shape. The u-shape helps to reduce pressure horizontally whereas the circular shape helps to reduce pressure vertically. Please keep in mind that installation and removal of siphons require a pressureless system, or else the medium could leak uncontrollably and become a hazard for both workers and the machine itself. A t-piece or a welded thread can be used to connect the siphon within the pipeline.
